The power supply cable is used for power supply, and the power supply detection cable is used for detecting the power supply voltage. Figure 1 As shown, this method includes

[0035] S1, obtaining a voltage difference between the power supply cable and the power supply detection cable.

[0036] In a specific implementation, the voltages of the power supply cable and the power supply detection cable are detected respectively, and the voltage difference between the power supply cable and the power supply detection cable is further obtained. The voltage difference may be the actual voltage difference between the power supply cable and the power supply detection cable, or a preset multiple of the actual voltage difference.
